So what is it with crab spiders? Why must they bite the head off their victims? Other predators are not nearly so insulting: Wolves take a chunk out of the middle, alligators take an arm or a leg, and snakes choke down the whole thing at once. But crab spiders have no tact.
“Crab spider” is a general term for many types of spiders that look and move like crabs, and many of them will eat bees. They don’t target bees specifically but will consume any type of invertebrate they can wrap their legs around.
I’m not a fan of spiders because they have too many legs. More importantly, when a creature’s eyes are arranged in rows, it creeps me out. But crab spiders attract my attention because I’ve watched them pluck foraging bees right out of the air and eat them, head first, with no social grace whatsoever.
The spiders in the photos below are Misumena vatia in the family Thomisidae. This species is able to change color from yellow to white to match the flower on which it sits. The great camouflage allows them to easily snare a meal. When the spiders remain white while sitting on a flower of a different color, such as the one on the California lilac below, their coloring is thought to mimic bird droppings and, as such, they appear to be harmless.
The crab spiders don’t spin webs, but ambush invertebrates when they visit a flower. They paralyze their prey with a venomous bite and then consume it at their leisure. The eight small eyes allow it to detect the slightest movement. True to their name they can move crablike forward, sideways, and backwards. When prey comes close, their forelegs rise up to strike in crab fashion. I photographed both of these smarmy creatures in my garden.
What great photos. You spent lots of time to get these!
Thanks for noticing! I love getting a good pic.
I have yet to see a spider of any kind decap the head off anything, let alone a bee. They just don’t have the mouth parts for it. They bite and then suck out the inners. Nice photos!
I have no doubt you are absolutely right as I know nothing about spiders. But that’s what it looks like to me from my api-centric point of view. Besides, it makes a good title.
Btw, “biting and sucking out the innards” sounds even worselike losing your brain through a straw.
I love spiders almost as much as I love bees. Almost. Very cool photos!
I love the picture of the spider eating the bee on the dandelion. The spider blends so well!
I love macro photography, and I imagine you had to be very patient to get those pictures. Can’t wait for you to share photography secrets.
Actually, Toby, I haven’t forgotten. I’ve been taking notes (I have many pages) so now I have to work it into something readable.
Here is one of my bees that was taken by a crab spider, http://flic.kr/p/czAdh1
Great photo. The spider crabs seem to like dandelions for hiding out.
You should search for these pictures periodically on the web. They are great and will probably get lifted by someone.
I just saw one of these buggers! I saw a bee hanging from a honeysuckle and was trying to figure out how the flower managed to hang it. My husband took a closer look and realized it was a spider. Freaky!
I saw a white spider yesterday on hogweed took and its picture. Then today went past the same flower and it was still there but there was a small bee on the spider’s back. Took 3 pics of it and to me, it appears that the bee is sucking the spider. Can I send you the pics? From all I read, it is the spider that kills the bee but it doesn’t look like that from my pics.
Are you sure it wasn’t a wasp?
